Certificates, certificate authorities, and machine identity at the scale AI demands — explained, automated, and operationalized without the legacy pain. Built for machines, workloads, and the AI agents that now need cryptographic identities too.
The Problem
Most organizations operate PKI on a combination of institutional memory, spreadsheets, and certificates that expire at 2 a.m. on a Saturday. That was always fragile — now it's untenable.
Certificates expire on forgotten schedules, taking down production systems at the worst possible moments — and no alert ever fired.
Nobody can enumerate every certificate in production. Shadow PKI runs in corners of the environment nobody monitors.
Workloads, containers, devices, and now AI agents all demand cryptographic identities. Manual PKI cannot scale to that population.
Post-quantum standards are arriving. Organizations with no crypto-agility face an emergency migration instead of a planned one.
The Solution
pki.ms covers the complete discipline of modern PKI — from CA hierarchy design to AI agent identity — with an emphasis on operational PKI that runs reliably, not PKI that lives in a binder.
Keys, certificates, CAs, intermediates, revocation, and chains of trust — explained precisely enough for practitioners and clearly enough for newcomers.
Root and intermediate CA structures that balance security, operational flexibility, and blast-radius containment — including offline root best practices.
Discover every certificate, automate issuance and renewal via ACME, and alert on everything that can't yet be automated. Expiry outages become a historical artifact.
Short-lived certificates for services, containers, and devices at scale — mutual TLS done right, with identities that rotate faster than attackers can exploit them.
Per-agent certificates, attestation of agent provenance, and signing of agent actions — so autonomy never means anonymity, and every agent action is attributable.
Inventory your algorithms, plan migration paths, and build the agility to swap cryptography as standards evolve — including the post-quantum transition on the horizon.
Deep Capabilities
How It Works
A repeatable operational journey — from not knowing what you have to running PKI that scales to the AI era without human intervention.
Inventory every certificate and key in your environment — including the forgotten ones quietly doing critical work on legacy systems that nobody documents. You cannot manage what you cannot see.
Establish or refine your CA hierarchy and certificate policies, with trust boundaries that contain compromise instead of amplifying it. Offline roots, intermediate tiers, compromise recovery — designed before you need it.
Move issuance, renewal, and revocation to automated pipelines using ACME and similar protocols. Eliminate the human-memory failure mode entirely — certificates renew themselves, every time, without a calendar reminder.
Issue cryptographic identities to the full machine population — services, containers, devices, and AI agents — with certificate lifetimes measured in hours. Trust scales; the attack surface doesn't.
Use Cases
Automated discovery and renewal means the certificate that used to take down the customer portal at midnight now rotates itself weeks before expiry — silently, reliably, every time.
Short-lived workload certificates give every microservice a verifiable identity, so east-west service traffic is authenticated and encrypted by default — the backbone of zero trust architecture.
Each agent holds its own certificate; its outputs are signed, making provenance verifiable and impersonation immediately detectable — critical as AI agents act autonomously on the organization's behalf.

Manual vs Modern PKI
| Dimension | Manual / Legacy PKI | Modern Automated PKI |
|---|---|---|
| Certificate inventory | Spreadsheet, always outdated | Continuous discovery, always current |
| Renewal process | Calendar reminder, often missed | Automated via ACME, zero human touch |
| Certificate lifetime | 1–2 years, rarely rotated | Hours to days, auto-rotated always |
| Expiry outages | Inevitable, unpredictable | Eliminated by automated renewal |
| Machine identity scale | Manual — doesn't scale to containers | Unlimited — scales to AI agents |
| Post-quantum readiness | Unknown algorithm inventory | Inventoried, agility built in |
| Compromise recovery | No rehearsed playbook | Documented, tested, ready to run |
Security & Future-Readiness
The cryptographic landscape is shifting. Post-quantum algorithms are standardized. Organizations that build algorithm agility now run an operation; those that wait run an emergency.
Know every algorithm in use across your certificate estate — RSA key sizes, ECDSA curves, hash functions — before the migration window arrives.
Architect systems to swap cryptographic primitives without application changes — abstract the algorithm layer so migration is operational, not architectural.
NIST post-quantum standards are finalized. The migration will take years — starting the inventory now means the eventual swap is planned, not panicked.
Air-gapped root CAs with hardware security modules — the root of your trust hierarchy protected against both external attack and insider threat.
Certificate policies, CPS documentation, and the evidence trail auditors need — built into operations from the start rather than assembled before each audit.
Rehearsed incident playbooks for intermediate and root CA compromise — so the question is never "what do we do now?" but "run the playbook."
